Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a damping wall incorporating a damping mechanism into a partition wall or the like of an apartment complex or the like.

(Conventional technology) In the seismic design of mid-to-high-rise and ultra-high-rise office buildings and apartment complexes, consideration has been given to the effect of internal damping for the vibration damping of structures; There was no way to create attenuation in a children's style.

(Problems to be Solved by the Invention) Therefore, the input amount and response deformation during an earthquake are limited, which often results in difficulties in livability against shaking during an earthquake.

(Means for Solving the Problems) The present invention relates to a vibration control wall proposed to solve the above problems. The above-mentioned problem is solved by interposing a damping material in the lower part or middle part of the high wall plate.

(Function) Since the present invention is configured as described above, at the time of an earthquake, a damping force is generated by sandwiching the damping material and creating a relative velocity between the upper and lower adjacent layers, the earthquake input port is reduced, and response deformation is achieved. is reduced.

(Example) The present invention will be explained below with reference to an illustrated embodiment T75.

In the actual example shown in Figure 2a1 and Figure 2, (1) is a highly rigid partition wall slab made of PC wall slab, and is loaded into the opening (2a) provided on the floor slab (2) surface. The wall slab (1) is supported on a damping material (3) made of a plastic metal such as lead or a viscoelastic material.

In the figure, (4) is a column, and (5) is a beam.

Since the embodiment shown in the figure is configured as described above, in the event of an earthquake, the space between the partition wall slab (1) and the floor slab (2) that are adjacent above and below the damping material (3) is A relative velocity is generated, a damping force is generated, the amount of seismic wave input is reduced, and the response deformation is reduced.

FIGS. 3 and 4 show another embodiment of the present invention, in which the partition wall slab is divided into a plurality of PC wall slabs (1a), and the middle of the vertically adjacent PC wall slabs (1a), A damping material (3) is interposed between the lowermost PC wall slab (1a) and the mouth height (2a) of the floor slab (2).

In the figure, parts equivalent to those of the above embodiment are given the same reference numerals.

The functions and effects of this embodiment are substantially the same as those of the embodiment shown in FIGS. 1 and 2, so the explanation thereof will be omitted.

Normally, the internal damping of a building is about 2% to 5%, but in the embodiment described above, the earthquake input and response deformation can be reduced by PC% to 30%, depending on the number of seismic walls arranged.

It is also particularly effective in preventing continuation of shaking in very high-rise buildings.

(Effects of the Invention) According to the present invention, as described above, a damping material is interposed in the lower part or the middle part of a highly rigid wall slab composed of a single PC board or a PC board divided into multiple parts. By using the same damping material, a relative velocity is generated between the upper and lower layers of the same material during an earthquake to generate a damping force, reducing the amount of seismic wave input, reducing response deformation, and improving livability against shaking during an earthquake. It is something to do.
